BTS 161202 Version 1
High-Pitched Whine with A/C Running
AFFECTED VEHICLES
2014−17 RLX
We’re getting reports of a high-pitched whine with the A/C running. It goes away when the A/C is turned off. Changing
the fan speed has no effect on the noise, and it seems to be worse with the engine running between 1,600 to 2,100 rpm.
From our investigation, we’ve found that this noise is coming from a resonance in the A/C compressor, which is getting
transmitted into the cabin through the refrigerant lines.
Until we have a solution available, avoid replacing components or doing a deep evacuation/recharge of the A/C system;
it won’t help.
